BOLT-CLIPPER.

SPECIFICATION forming part of Letters Patent No. 737,198, dated August25, .1903.

Application filed September 8.1902. Serial No. 122,503. (No model.)

To all whom it may concern:

Be it known that I, GOTTLIEB BINDER, a citizen of the United States,residing at Louisville, in the county of Jefferson and Stateof Kentucky,have invented certain new and useful Improvements in Bolt-Clippers; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to Which itap- IO pertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specication.

This invention relates to improvements in r 5 cutting devices, and moreparticularly to an f improvementV in boltclippers in which the cuttingforce is applied by .vertical instead of horizontal leverage; and theobject of the invention is to provide a most simple, efficient,

' zo` compact, and durable tool for cutting olf the ends of bolts. 5' ll To this end the invention essentially consists of a tool having astationary and a pivoted handle and having its body formed With z5 anopening through which one endv of said pivoted handle extends when thetool is opened, said body having a member of the,

cutting device at its endv remote from the handle and a plunger mountedto reciprocate 3o in said body and having at one end the other cuttingmember and a spring for moving the plunger in one direction, saidplunger and movable handle having contiguous ends, which are curved inreversed directions.

In the drawings, Figure l represents a top view of .my bolt-clipper whenclosed With the handles partly cut away. Fig. 2 represents a verticallongitudinal sectional view, on a mc- Y dial line, of my clipper whenpartly open for 4o the admission of a bolt with handles-partly cut away.Fig. 3 is atop view ofa modified form of my clipper adapted to receivethe end of the bolt to be clipped from the side instead of from thebottom. Y

In the drawings, A represents thev body of my bolt-clipper, rectangularin cross-section and having a rectangular bottom to receive a plunger B,similarly rectangular in cross-section, its inner end B curvedeccentrically to 5o engage the eccentric end C of a handle H, pivoted ona bolt D, journaled in the sides vof the ting-knife b.

frame A and its outer endbearing a cuttingknife b. Against the outerendof the frame A and v'vithin it is placed a steel block E, as shown,having a cutting edge e, its edge opposite to and parallel with the edgeof the cut- In the bottom of the frame A, under the knives when thecutter is closed, is an aperture to admit the endof the bolt to be cutwhen the bolt-cutter is open for action. 6o

F represents a coil-spring, one end of which is fastened to a post J, inthe bottom of the plunger Bnear the end bearing the knife, and the otherto a post K in the top of a removable picce G. forming a bottom to partof the frame A. The bottom ofthe frame A is eX- tended backwardly toform arigid handle H and is formed with an opening G', through which theeccentric end C of the handle Hprojects When the opposite end of said:handle is' 7o raised. Attention is called to the fact that the engagedends of the movable handle and plunger are curved in opposite directionsand are relatively such asto cause said plunger to be`moved through acomparatively great distance with maximum ease and that by forming thebody or frame ofthe tool beneath the eccentric C with an opening throughwhich said eccentric projects when the handle H is l -raised the deviceis made most compact in 8o construction. The frame and handles arepreferably made of malleable iron.

I represents a set-screw in the fixed handle adapted to take up the wearin the knife b.

The operation of my bolt-cutter may be de- 8 5 scribed as follows: Whenit is desired to cut the end off a bolt, the pivoted handle H is raiseduntil its eccentric endy Gand handle H take the position indicated bythe dotted lines in Fig. 2, the eccentric taking about the 9o positionC', when the spring F causes knifebearing plunger B to follow theeccentric and uncover the aperture in the bottom ofA between the cuttingedges of the knives.- Then the bolt end is inserted in.- the aperture,`the handles are grasped by the operator and the handle H is depressedvertically, the knifebearing plunger B is pressed forward against thebolt, which is pressed against the knifeedge e till severed. greaterleverage can be obtained by the pivv oted handle pressing downvertically then by It is apparent that aY rooY pressure exertedhorizontally. To cut a bolt so placed that its end eannotbe inserted inthe aperture in the bottom of the frame, so as to secure verticalleverage'on the knives, I provide an aperture M, as shown in Fig. 3, inthe side of the frame by which the bolt can be inserted betweensuitably-arranged knives. In this case the frame should be strengthenedby a rib L, extending around the side opposite the aperture M and theend.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is-

1. A bolt-clipper, comprising a frame having a cutting member at one endand a stationary handle at its other end, and also having an openingadjacent to said handle, and provided between said opening and cuttingmember with a removable bottom plate; a plunger in said frame, mountedto reciprocate above said removable bottom plate, said plunger having acutting member at one end and its other end curved, a pivoted handle forpressing the plunger in one direction, said handle having at one end acam arranged to project through said opening in the frame when thehandle is raised, said cani being curved in a direction the reverse ofthat of the curved end of said plunger and engaging the same, and aspring acting in opposition to said cam and arranged in a space betweensaid removable bottom and the under side of the plunger, substantiallyas described and for the purposes set forth.

2. A bolt-clipper, comprising a frame having a chamber at one end and afixed handle at its other end and provided with a removable bottom platefor its said chamber, supporting means above said bottom plate,a plungermounted to reciprocate in said chamber, on said supporting means and outof contact with said bottom plate, a spring for adjusting said plungerin one direction, said spring being secured to the plunger and frame andlocated in the space between the plunger and the removable bottom plate,a cutting member at one end of said chamber, a cutting member carried bysaid plunger, and a pivoted handle having a cam to engage said plungerand adjust the same in opposition to said spring.

3. A bolt-clipper, comprising a frame having a cutting member at one endand a stationary handle at its other end, said frame having astrengthening-rib at one side and an aperture at the bottom oi' itsother side, said aperture extending transversely of the frame from aplace contiguous to the cutting member thereof, a plunger mounted toreciprocate in said frame and provided with a cutting member at one end,and a pivoted handle engaged with the other end of said plunger andoperated to adjust the same.

4. A bolt-clipper, comprising a frame, having a chamber at one end, afixed handle at its other end and a laterally-extending aperture at thebottom, and provided with a removable bottom plate for its said chamber,supporting means above said bottom plate, a knife at one end of saidchamber, contiguous to said aperture, a plunger mounted to reciprocatein said chamber and on said supporting means and out of contact withsaid bottom plate, a spring ,for adjusting said plunger in onedirection, said spring being secured to the plunger and frame andlocated in the space between said plunger and removable bottom plate, aknife carried by said plunger and presented to the knife of said frame,and a pivot-ed handle having a cam to engage said plunger and adjust thesame in opposition to said spring, substantially as shown and described.

In testimony whereof I aiiix my signature in presence of two witnesses.
